Question 1
Given a BJT with a minimum β of 100 and a target filter response of 3 mA for IC, design the circuit with a VCC of 12 V and calculate the stability under temperature changes.
💡 Hint: Start with the calculations of all parameters before adjusting for stability.
Question 2
How would you redesign a Fixed Bias circuit to incorporate a Voltage Divider while achieving the same target Q-point? Provide a thorough explanation of alternative arrangements and expected results.
💡 Hint: Focus on the influence of the new base voltage on stability.
